Hi, I would like to buy the template "ja-property"

I have a few questions about:
Question 1
I'm on the page: https://ja-property.demo.joomlart.com/index.php/properties/properties-grid#sort=position&sortdir=desc&attr.cat.value=15&page=1 and here I should see all the properties in the area of San Francisco. The advanced search says that there are 4 properties in the San Francisco area and shows them correctly on the right side of the page. The problem is that in the left part of the page, where I see the map, the properties are 5 and they belong to another area (see attachment)

Question 2
In the advanced search I see the entries "bathroom", "bedroom" ... can I add more? Such as "Garage", WiFi ", "heating type" and others?

Question 3
Is it possible to put in order the results according to "featured"? I would like that highlighted properties appear first (ordered by publication date) and then all the others. Is it possible?

Question 3
Is it possible to manage the zone fields in the search filter? For example ... I would like to disable the city field and condition it to region field. Once the user selects the region, the city field must be activated with all the places belonging to that particular region. It is provided?

I really like the template and I could decide to buy it, but I have to understand problem linked to the map and all the other functions I need.

Thank You!
Best Regards
